Applicationfiledmarch 11,1912; Seria1-No.68 973..

residing at Detroit, county of Wayne, State of; Michigan, have invented a certain new and useful Improvement in Clutches, and declare the following to be a full, clear, and

exact description of the same, such as will.

enable others skilled in th'e'art'to which it pertains to make and use the same, reference being had to the accompanying drawlngs,

h. f part of this specification.

My invention relates to clutches and conscribed and pointed out'in the claim.

In the accompanying drawings,'-Figure l is 'a sectionalplanview of an apparatus embodying my invention. Fig. 2, is'a detail elevation partly in section on the line 22 Fig. 1 looking from the left of said line. Fig. 3, is a detail view illustrating amethod' of securing the clutching springs. I

D, D isthe gear case having end walls and E. I

A, is a shaft resting in a'bearing in the end wall G and extending toward the end wall E, and in the p'resentcase extending into the plane of thewall E. i v

G, is a radial and thrust ball bearing resting in an aperture in the end wall E.

F, is aplate securing the bearing G in place. g

J, is a hollow shaft resting in the bearing G and sleeved upon the'shaft'A.' The shaft A is provided witha squared portion A to- 1 ward its right hand end and extendsrtherefrom to the left in the'portions A ,anc'l S, is a shaft resting in a bearing R'ln' the wall C.

I, is a radial and thrust ball bearing rest ing in an aperture in the wall E and held in place by a cover plate H.

T, is a sleeve rotatable upon the shaft S and resting in the bearing 1. The shaft S extends through the sleeve T and into the plane of the bearing 1.

U, V, W, X, are gear wheels of difierent diameters keyed upon the sleeve T.

P and Q, are gear wheels adapted to'slide on a feather on the shaft J The shafts A and S are parallel and the gear wheels P and Q are adapted to engage gear wheels upon the sleeve T.

O, is a gear wheel sleeved upon the portion A of the shaft A, its teeth engaging the teeth of the gear wheel U. The gear wheel .P' is provided" a toothed ran sra 'r ns arana emea I adapted to engage a corresponding clutch on the gear wheel 0 so as to" connect the shaft J directlyto' the'gear wheel 0.

K, is ahollow .drum secured to the squared portion A ofthe shaft A. Thecylindrical L, is a drum sleeved about the shaft A Within the drum Kcand having its cylindricalwalls parallel'to said shaft and to the corresponding 'walls of thedrum K.

'Wallsof the 'drum K are parallel to the shaft I i i 7c, are friction plates engaging the drums 'Lland. K of such' a construction that when 'saidpl'ates are pressed together they shall bindsaid drums t0-'gether.- The hub of the drum L adj acent" to" the gear wheel 0 is providje'd with-"a toothed clutch" member which engages a corresponding member on the hub of the gear wheel 0. I

N, isa presser-disk s'leeved upon the hub of'the drum L. andadapted to move longitudinally of the axis of said hub and of the shaft A; A means, not shown, but'which willbe readily supplied by those conversant with the art, is contemplated, by which the with the friction plates. The periphery of the disk N normallyre'sts against the left hand one of the annular friction plates 70.

The drum L is provided with lugs at'its peripljiery whiclrextend through slots'pin the disk N so: as to restrain relative angular movement of said disk and drum. .1 I

s, is a flange upon the'drum ;L extending in a plane atright angles to the axis of said connected to the flange 8 within the'cylin.

disk N'may be drawn out of engagement i drical peripheral walls of the drum L and the other end of the spring is secured to the disk N, as hereinafter described. The action of the springs M, M is to draw the disk N inward pressing its periphery against the friction plate is and causing said plates to engage each other and bind the drums K and L together. By moving the disk N outward the friction is relieved on the disk 70 and the drums K and L are free to turn independent of each other."

h, is a bushing surrounding the portion A of the shaft A and bearing against the interior of the shaft J.

g, and f are bushings surrounding the 1501- tion A of the shaft A and provided respectively with outwardly extending annular flanges z and j which flanges are contiguous and are interposed between the gear wheel Q and the adjacent end of the shaft J. The sleeve 9 rests in the bore of the shaft J and the bushing f is within the gear wheel 0 and carries said gear wheel.

e, is a bushing within the hub of the drum L and carryingsaid drum. The bushing e is provided with an outwardly extending annular flange m which passes up against the inner end of the hub of the drum L.

(Z. is a washer interposed between the annular flange m and the hub of the gear wheel K. The washer d may be OI such a thickness as shall take up the lost motion which would otherwise occur between the sleeve J, gear wheel 0 and drum L and thus any imperfection of workmanship may be compensated for.

The'outer or left hand ends of the springs M are secured to the disk N in the following manner: Referring more particularly to Figs. 2 and 3, a is a wire or small bar bent in a loop 11, at its center and bent at right angles at its ends to form the portions 9, g, which pass into or through apertures r, 1' located in the disk N at equal distances from an aperture a in the disk N. When the portions g, g of the wire a extend into the apertures r, r the loop a extends into the aperture a, as shown in Fig. 3. A hook formed upon the end of the spring M engages this loop and thus the spring is secured to the disk N.

T T are split rings adapted to fit into grooves t 6 around the ends of the sleeve T. The gear wheels are placed upon the sleeve T and the rings T are then snapped into the grooves t to hold the wheels in place.

By placing the springs M Within the drum L room otherwise not occupied is made available and greater compactness of the mechanism is secured. The parts may be easily adjusted to position and removed for inspection and repairs. 7 The end plate E may be removed carrying the bearings G and I and the sleeves T and J with it. The gear wheel 0 may be removed by simply sliding it along and over the extension of the shaft A. These parts may be placed in position by simplv sliding the gear wheel 0 over the extension of the shaft A, its hub provided with a clutch part automatically engaging the clutch part on the hub of the drum L. The sleeves T and J simply slide in position over their respective shafts. When the end plate E is bolted to the casing D the parts are firmly secured in position. Obviously as the openings for the bearings I and Ur are made large enough one of said bearings for the sleeve and attached parts maybe removed without the other.

What I claim is A clutch having an outer and an inner drum-like part, annular presser plates located between the peripheries of said drums and adapted to form a frictional engagement between the same, a presser disk forming substantially the end of said outer drum, its periphery engaging against said presser plates, and a tension spring located within the inner drum, one end engaging said presser plate and the other endengaging a portion of the inner drum, and means for preventing relative angular movement between said inner drum and said presser plate.

In testimony whereof, I sign this specification in the presence of two witnesses. BOUDEVVIJN B. NEUTEBOOM. Witnesses:
